I'm a fan of he IMAX B6
The IMAX B6A6 has a built in power supply and its a digital charger and can charge 99% of the battery's out there, it has functions and modes that u might of never seen before...
As for lipos.... Get the cheapest u can... They work a treat
This is a very good start...I've been using these with great success, I'm 99% sure it will fit...
